using Jogl with Eclipse RCP ?

Hi everybody,

here is my problem :
I try to use some Jogl code in an eclipse RCP project, but I have the following message :

Unhandled event loop exception
Reason:
net/java/games/jogl/GLEventListener

I have installed the OpenGL plugin and (I think ;D) everything needed to work, but it doesn’t work !!! >:(
What have I missed ? ???

Thanks a lot
